I am worried that I have made a daft choice. I recently bought a Marantz SR4200 amp for music and home cinema use and a pair of Wharfedale Diamond 8.2s to use with it. I am not completely satisfied with the sound I get from the 8.2s and am wondering if I should use these as rears and get a pair of floorstanders for the front speakers. The problem is that the sound doesn't seem quite as full as my old Sony system, I am wondering if I am expecting too much from a pair of bookshelf speakers. Would biwiring make much of a difference to my wharfedales, perhaps they need "breaking in"?? I am unsure. Should I just try to sell them and get a pack like the Mission pack from Richer Sounds?
